Changes in the fractionation scheme of radiotherapy course have an impact on results treatment cancer patients. If changes are not taken into account, this leads to under-irradiation tumor cells and a possible occurrence subsequent relapses. There radiobiological models order take account errors radiation dose delivered tumor. They allow predicting control, as well toxicity level normal tissues...

The feasibility of using the active layer of the colorless LR 115 SSNTD for alpha-particle radiobiological experiments was studied. The track revelation time on the bottom side (the side attached to the polyester base) was much longer than that on the top side (the side not attached to the polyester base) of the active layer so track formation on the top side was more desirable. In relation to ...

The aim of radiation oncologist is to implement an uncomplicated loco regional control of cancer by radiation therapy. The bioeffect of a physical dose depends on the nature of the tissue, fractionation scheme, dose rate and treatment time. The transformation of absorbed dose into a bioeffect dose is controlled by treatment variables and the radiobiological characteristics of the relevant tissu...
